Expanding on what @daniel suggested it might be worth speaking to someone from the eazyBI team because I know they’ve achieved this:
Their main app for JIRA:
https://marketplace.atlassian.com/plugins/com.eazybi.atlassian-connect.eazybi-jira/cloud/overview
A suppporting app for Confluence that allows you to embed their reports into a Confluence page:
https://marketplace.atlassian.com/plugins/com.eazybi.atlassian-connect.eazybi-jira-confluence/versions
They’ve hidden the second Confluence app from marketplace.atlassian.com so it can only be found via UPM within Confluence. I assume this is so people are less likely to start in the wrong place and allows them to better do SEO.
